2.3 Installation

The bicarb system ships ready to operate. There are two system connections:

- Inlet (feed water): 3/4” schedule 80 PVC

1” schedule 80 PVC - Drain:

NOTE: For the feed water line, we recommend that a valve be placed prior to the system for emergency system shut-off and that a 3 GPM flow restrictor also be installed to limit the amount of water that can be drawn off of the water system.

NOTE: For cleaning, we recommend a bypass around the flow restrictor to allow the unit the fill faster. This should substantially reduce the clean and disinfection time of the unit.

NOTE: Unions should be installed on all connections to allow the unit to be moved for servicing. Connections may be made with tubing.

CHAPTER FIVE: SYSTEM CLEANING AND DISINFECTING

5.1 Introduction

NOTE: Disinfecting should be done every night after system operation unless proven documented results in accordance with customer’s policies and procedures demonstrate otherwise so as to maintain bacteria and endotoxin levels that are in accordance with AAMI standards. It is recommended that the system be disinfected on a weekly basis.

For disinfecting, the recommended total contact time for the bicarb system is one (1) hour. This includes introducing the approved disinfecting agents (1% peracetic acid or household bleach 1% mixture by volume), recirculating the solution through the system, testing for positive presence at each point, dwell time, and rinsing. If less time

(for example 30-45 minutes) is practiced and still maintains acceptable culture results than that can be used as an approved maintenance practice. However, if higher culture counts are noted than a change in the practice is required. Mar Cor Purification recommends that the system be rinsed every night following normal system operation.

1. There are 3 basic steps to disinfecting the bicarb system: a. STEP 1: System Pre-Rinse (Section 5.2) – designed to rinse bicarb from the system. This procedure should be done nightly after normal operation. b. STEP 2: System Disinfecting (Section 5.3) – procedures for cleaning/disinfecting the bicarb system. c. STEP 3: System Rinsing (Section 5.4) – procedures for rinsing out the cleaning/disinfecting solution in order to return the system to normal operation.

WARNING: System disinfecting should NOT be done while the bicarb system is in use for patients or possible harm could occur.

5.2 Bicarb System Pre-Rinse

1. After completion of jug filling (either method), drain any solution using valve V4.

2. Close valves V2, V3, V4, V5, and Jug Port.
